Field of the Invention This invention relates to a bracket for mounting a toe board along the edge of a scaffold plank or similar structure.

2. Description of the Prior Art Most prior bracket arrangements known to applicant are designed to mount the toe board member on the top surface of the plank. This arrangement not only reduces the amount of available walking surface on the plank but is susceptible to the existence of a gap between the plank and the toe board in the event there is any tendency of the planking to sag between its supporting members. One of the principal objects of this invention is to provide a toe board bracket wherein the toe board is mounted adjacent the edge of the scaffold plank to thereby provide-a maximum walking area on the plank and to eliminate the gap problem referred to above. Another object is to provide a bracket which has a relatively simple construction and can be installed easily.

SUMMARY OF THE INVENTION A toe board bracket including a toe board holding portion comprising a pair of spaced inner and outer vertically extending legs adapted to receive the toe board therebetween and a horizontal gripping portion comprised of a pair of upper and lower spaced horizontally extending legs adapted for gripping engagement with the edge of a plank member. The lower leg of the gripping portion is formed integrally with and extends from the base of the inner leg of the toe board holding portion. The upper leg of the gripping portion is formed integrally with and extends from the middle portion of the inner leg of the toe board holding portion. The bracket is made from a resilient material such as extruded aluminum with the outer leg of the toe board holding portion and the lower leg of the horizontal gripping portion curved to form a resilient spring arm to provide frictional engagement between the legs of the respective portions and the members positioned between the spaced legs thereof.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a fragmentary perspective view showing several toe board brackets of the present invention installed in position on a scaffold plank; and

FIG. 2 is a fragmentary end view of the assembly shown in FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings in detail, the toe board bracket of this invention is identified by reference numeral and is comprised of a horizontal gripping portion 12 designed for gripping a horizontal member such as a plank 14 and a toe board holding portion 16 for receiving a toe board member 18.

The two portions 12 and 16 of the bracket 10 are formed integrally with each other. In the preferred embodiment the bracket 10 is made from a resilient material such as extruded aluminum which can be manufactured as an elongated extrusion and then cut into brackets of the desired width which in the preferred embodiment are 1 inch wide.

Portion 16 is comprised of a pair of spaced vertically extending legs 20 and 22 and a base leg 24. Leg 20 is curved as shown in FIG. 2 to form a spring arm to frictionally grip toe board 18. Arm 20 is provided with a nose portion 26 of increased thickness to facilitate driving the plank gripping portion 12 into engagement with plank l4.

Portion 12 is comprised of a pair of spaced horizontally extending legs 28 and 30. Leg 28 extends from and is integral with lower portion of leg 22 and in effect is an extension of base leg 24 of portion 16. Leg 30 is integral with and extends from the upper central portion of leg 22 of portion 16.

Leg 28 is curved as shown in FIG. 2 to form a spring arm to frictionally grip plank member 14. By curving the legs 20 and 28, as shown, the area of contact between the legs and the plank and toe board respectively is concentrating at areas 32 and 33 to thereby provide a relatively tight gripping action between such legs and the plank and toe board.

Leg 30 is provided with a plurality of teeth-like ridges 34 on the lower face thereof. Such teeth tend to dig into the surface of plank 14 when installed thereon. The faces 36 of ridges 34 angle upwardly at a much deeper angle than the opposite faces 38 to thus provide easy installation thereof and yet provide the desired gripping action once they are installed. A hole 40 is provided in leg 30 for installation of an anchoring nail 42.

In a typical installation as shown in FIG. 1, a plurality of toe board brackets 10 are installed along the outside edge of a scaffold plank 14 by first driving each bracket horizontally over the edge of the plank until the plank is fully seated between arms 28 and 30 of gripping portion 12 as shown in FIG. 2. The bracket is driven into position by a hammer or other similar tool by striking the bracket on nose portion 26. A nail 42 can then be driven into the plank through opening 40 to securely anchor the bracket in place.

After the brackets have been installed as described above, the installation is completed by the insertion of toe board members 18 which is accomplished by simply inserting each toe board into toe board holding portions 16 from above. The weight of the toe board 18 in the brackets 10 will tend to cause the arm 30 of each bracket to be pulled down and to the right as viewed in FIG. 2 which will tend to cause teeth 34 to dig into the surface of plank 14.

The dimensions of bracket 10 are of significance. Since 2 inches planks or boards (actual thickness l /zinches) are generally used for scaffold planking, arms 30 and 32 are dimensioned to fit snugly over a member having an actual thickness of 1% inches. Arms 20 and 22 are dimensioned to provide a tight fit with a 1 inch board (actual thickness three-fourths inch). By constructing the bracket 10 so that the lower edge of toe board 18 is at substantially the same level as the lower face of plank 14 (see FIG. 2), a toe board cut from a length of 1 inch X 6 inches lumber (actual inch thick and 5 /2 inches width) when installed will provide a 4 inches high protective wall along the edge of the scaffold plank. This is the minimum height required under most safety regulations. Thus the bracket is adapted for use with commercially available standard-size lumber,

namely, 2 inches planks and 1 inch X 6 inches boards.

Another advantage of mounting the toe board 18 adjacent the edge of plank 14 as opposed to mounting it on the top surface thereof (as is the case with many prior mounting arrangements), is that any tendency of the plank to sag or bow in the middle will not create a gap between the bottom edge of the toe board and the top of the plank as would be the case if the toe board were mounted on the surface of the plank. Such a gap is undesirable since it might result in items such as workmens tools to be accidentally kicked through the gap in which event they would then fall down to the ground below.

I claim:
